💡 Quick Study Guide: Repeating Actions in ScratchJr
- 🔄 The "Repeat" block in ScratchJr helps characters do the same thing many times without needing lots of blocks.
- 🔢 You can choose how many times a character repeats an action by changing the number on the repeat block.
- 🚶♀️ If you want a character to move 5 steps, 3 times, you'd put a "move" block inside a "repeat 3" block.
- ⏳ Repeating actions make your code shorter and easier to read!
- 🎨 It's great for making characters walk a path, jump, or spin multiple times.
